[0028] In order to reduce the splashing of cutting fluid and flying chips during sawing and to protect the personal safety of operators, the present application provides an embodiment one:

[0029] Please refer to Figures 1-6 In the present application: a steel plate saw milling machine water curtain mechanism, comprising a saw milling machine body 1, the top of the saw milling machine body 1 is provided with two mounting seats 2, the bottom of the right mounting seat 2 is fixedly connected with the saw milling machine body 1, a protective plate 3 and a limiting baffle 4 are fixedly connected between the two mounting seats 2. Track grooves 5 are formed in the two mounting seats 2, a water curtain shaft 6 is slidingly connected in front of the two track grooves 5, lifting mechanisms 7 are arranged on the two mounting seats 2, nylon rollers 8 are arranged at equal distances on the water curtain shaft 6 and are rotatably connected with the water curtain shaft 6, stainless steel foils 9 are wound on the nylon rollers 8, limiting grooves are formed in the limiting baffle 4, the inner walls of the limiting grooves are slidingly connected with the stainless steel foils 9, and large counterweights 10 and small counterweights 11 are detachably connected to the two ends of the stainless steel foils 9; the lifting mechanism 7 comprises an air cylinder 701, the fixed end of the air cylinder 701 is fixedly connected with the mounting seat 2, the telescopic end of the air cylinder 701 penetrates through the mounting seat 2 and is fixedly connected with a lifting block 702, and one side of the lifting block 702 is sleeved on the water curtain shaft 6 and is fixedly connected with the water curtain shaft 6.

[0030] In the present application, the water curtain is raised before sawing (as shown in Figure 2 In order to facilitate the passage of materials, the water curtain is first raised to the highest position, both air cylinders 701 are opened at the same time, the air cylinders 701 are ventilated, the air cylinders 701 drive the lifting block 702 to drive the water curtain shaft 6 and the nylon roller 8 to realize upward linear motion, the small counterweight 11 pulls up the stainless steel foil 9 through the nylon roller 8 under the block of the limiting baffle 4, and the large counterweight 10 is separated from the workbench, so that the steel plate before sawing can pass through conveniently.

[0031] The water curtain falls during sawing (as shown in Figure 1As shown in the figure), the saw blade needs to open the cutting fluid in the sawing work, in order to prevent the cutting fluid from splashing, the water curtain needs to be lowered, first, two air cylinders 701 are ventilated, two air cylinders 701 drive lifting block 702 to drive water curtain shaft 6 and nylon roller 8 to realize downward linear motion. Through the nylon roller 8, the stainless steel foil 9 is lowered, the large weight block 10 pulls the front end of the stainless steel foil 9 to fall on the steel plate, and the area without the steel plate falls on the workbench surface, so that the area of the sawing cutting fluid and the front operation area are completely separated, reduce the splashing phenomenon of cutting fluid and flying dust in the sawing process, at the same time, increase the safety of the operator.

[0032] In use, a plurality of stainless steel foils 9 form a complete water curtain, which can effectively shield the cutting fluid and flying dust splashing, but the stainless steel foil 9 is easily damaged during long-term work, and the stainless steel foil 9 needs to be replaced. In order to facilitate the replacement of the stainless steel foil 9, the present scheme provides embodiment two:

[0033] Please refer to Figures 4-6 Wherein: the shape of the large weight block 10 is U-shaped, the inner side of the large weight block 10 is in contact with the stainless steel foil 9, the large weight block 10 is provided with a screw hole 12, the inner wall of the screw hole 12 is threadedly connected with a connecting rod 13, the connecting rod 13 is inserted into the stainless steel foil 9 and is in sliding connection with the stainless steel foil 9; the shape of the small weight block 11 is U-shaped, the inner side of the small weight block 11 is in contact with the stainless steel foil 9, the small weight block 11 is provided with a threaded hole 14, the inner wall of the threaded hole 14 is threadedly connected with a plug rod 15, and the plug rod 15 is inserted into the stainless steel foil 9 and is in sliding connection with the stainless steel foil 9.

[0034] In the present application, the connecting rod 13 and the plug rod 15 are inserted into both ends of the stainless steel foil 9, so that the large weight block 10 and the small weight block 11 can be installed respectively. When the stainless steel foil 9 needs to be replaced, first rotate the connecting rod 13, then the connecting rod 13 is pulled out of the stainless steel foil 9, at this time the large weight block 10 is detached from one end of the stainless steel foil 9, then the stainless steel foil 9 is pulled out of the limiting slot on the limiting barrier 4, after the stainless steel foil 9 is pulled out, the plug rod 15 is rotated, the plug rod 15 is rotated out of the threaded hole 14, after the plug rod 15 is pulled out of the stainless steel foil 9, the small weight block 11 is detached, then a new stainless steel foil 9 is wound around the nylon roller 8 and one end is pulled out of the limiting barrier 4, then the large weight block 10 and the small weight block 11 are respectively clamped into both ends of the stainless steel foil 9, then the plug rod 15 and the connecting rod 13 are rotated, until the connecting rod 13 and the plug rod 15 respectively pass through both ends of the stainless steel foil 9, then the replacement of the stainless steel foil 9 is completed, the process is very convenient and fast, and the damaged stainless steel foil 9 can be replaced, without the need for overall replacement, compared with the overall water curtain damage, which effectively reduces the material loss and reduces the use cost.

[0035] Please refer to Figure 5 Wherein: the bottom of the large counterweight 10 is provided with a mounting groove 16, and the inner wall of the mounting groove 16 is fixedly connected with a buffer strip 17.

[0036] In the application, the mounting groove 16 can install the buffer strip 17, and the large counterweight 10 will contact with the steel plate after descending. The setting of the buffer strip 17 can reduce the impact and play a buffering effect, effectively reduce the wear of the large counterweight 10, and avoid the situation that the top of the steel plate is scratched, thereby improving the practicability of the device.

[0037] Please refer to Figure 6 Wherein: the bottom of the limiting baffle 4 is embedded with a rubber block 18, and the bottom of the rubber block 18 is in contact with the small counterweight 11.

[0038] In the application, the setting of the rubber block 18 can play a buffering effect on the small counterweight 11, reduce the impact force of the small counterweight 11 on the limiting baffle 4, reduce the generation of noise, and prolong the service life of the device.

[0039] The above is only a preferred specific embodiment of the application; however, the protection scope of the application is not limited to this. Any person skilled in the art can make equivalent replacements or changes to the technical scheme of the application and the improved concept thereof within the technical range disclosed by the application, which should be covered in the protection scope of the application.
